A bone: Spur in the low neck pressing on the sac which contains the cerebrospinal fluid protecting the spinal cord.

Degenerative changes: Degenerative changes in the cervical spine cause the vertebral body to form bone spurs. The bone spurs then encroach into the spinal canal. The first thing to happen next is the the structure around the spinal cord is displaced or compress by the spurs. In this case the dural sac that surrounds the spinal cord.

My MRI show wedging to my d-10 and d-11 due to previous trauma. Can you explain what this means?

Dr. Chintan Sampat
Orthopedic Spine Surgery 18 years experience
A broken bone: Wedging of t10 and T11 is a change in the shape of the vertebral body part of the spine. The bone gets crushed from an injury and can change shape from its normal rectangular appearance to a more wedge shaped appearance. This can also be a normal finding from degeneration of the spine due to aging as well as due to genetic conditions such as scheurmann's disease.
